Protecting expatriates in hostile environments: institutional forces influencing the safety and security practices of internationally active organisations
© 2017, © 2017 Informa UK Limited, trading as Taylor & Francis Group. The operations of internationally active organisations continue to encroach on hostile locations that are vulnerable to the negative consequences of crises such as political upheaval, terrorist attacks or natural disasters. Yet research into how firms ensure the physical and psychological safety and security of international staff in these locations is limited. This article reports an empirical study exploring the expatriate safety and security practices of 28 internationally active organisations from three industries that commonly operate in hostile environments. We unveil starkly different approaches across the three industries, and label these approaches ‘regulatory’ (mining and resources), ‘informal mentoring’ (news media) and ‘empowering’ (international aid and development). We use institutional theory to propose that these configurations reflect legitimacy-seeking choices that these organisations make in response to the various institutional environments that affect each sector. Our results provide a platform for initial theory building into the interrelated elements of organisations’ safety and security practices, and the institutional factors that shape the design of these
Decrease of Morbidity and Cost of Care with Prophylactic Cranial Irradiation for Non-small Cell Lung Cancer
Purpose: While several studies analyze the incidence of brain metastases in patients with non-small cell lung cancer (NSCLC) treated with prophylactic cranial irradiation (PCI), there is little data available on how this treatment can affect medical cost and morbidity. Our goal was to analyze those issues patients encounter secondary to brain metastases, often in the final months of their lives, and to support the hypothesis of economic benefit and cost effectiveness resulting from the use of PCI in this population.

Comparison of outcomes in patients with abandoned versus extracted implantable cardioverter defibrillator leads
SummaryBackgroundDespite the increased number of implantable cardioverter defibrillator (ICD) recipients and the frequent need for device upgrading and/or occurrence of lead malfunction, the optimal approach to managing abandoned leads remains debated. Aims To determine the rate and type of complications related to either abandoned or extracted ICD leads. Methods Patients with abandoned or extracted leads were identified retrospectively. Patient medical records were reviewed to assess long-term lead or device malfunction, defibrillation test values before and after lead abandonment or extraction, and appropriateness of delivered shocks and subsequent surgical procedures related to devices or leads. Results A total of 58 ICD patients with 47 extracted and 34 abandoned leads were identified. After a mean follow-up of 3.2 ± 2.6 years, the defibrillation test was not affected by either abandoned or extracted leads (23.4 ± 6.6 J vs 25.4 ± 4.9 J, respectively; P = 0.24). There were no differences in the number of ICD-related surgical procedures after extracting versus abandoning leads (22% vs 12%, respectively; P = 0.3) or in the thromboembolic event rate (7.7% vs 6.3%; P = 0.83). During follow-up, no differences in the occurrence of major complications or appropriate/inappropriate shocks were observed between patients with or without abandoned leads. Conclusion We observed no difference in rates of immediate or medium-term complications between extracting versus abandoning leads. Lead abandonment remains an alternative and safe option when extraction does not appear mandatory according to the age of the leads or experience of the operating centre

Cost Shared Wildfire Risk Mitigation in Log Hill Mesa, Colorado: Survey Evidence on Participation and Willingness to Pay
Wildland–urban interface (WUI) homeowners who do not mitigate the wildfire risk on their properties impose a negative externality on society. To reduce the social costs of wildfire and incentivise homeowners to take action, cost sharing programs seek to reduce the barriers that impede wildfire risk mitigation. Using survey data from a WUI community in western Colorado and a two-stage decision framework, we examine residents’ willingness to participate in a cost sharing program for removing vegetation on their properties and the amount they are willing to contribute to the cost of that removal. Wefind that different factors motivate decisions about participation and about how much to pay. Willingness to participate correlates with both financial and non-monetary considerations, including informational barriers and wildfire risk perceptions, but not with concerns about effectiveness or visual impacts. Residents of properties with higher wildfire risk levels are less likely to participate in the cost sharing than those with lower levels of wildfire risk. We find widespread, positive willingness to pay for vegetation removal, with the amount associated negatively with property size and positively with respondent income. These results can inform the development of cost sharing programs to encourage wildfire risk mitigation on private property
Red fluorescence of the triplefin Tripterygion delaisi is increasingly visible against background light with increasing depth
Red fluorescence of the triplefin Tripterygion delaisi is increasingly visible against background light with increasing depth
The light environment in water bodies changes with depth due to the absorption of short and long wavelengths. Below 10 m depth, red wavelengths are almost completely absent rendering any red-reflecting animal dark and achromatic. However, fluorescence may produce red coloration even when red light is not available for reflection. A large number of marine taxa including over 270 fish species are known to produce red fluorescence, yet it is unclear under which natural light environment fluorescence contributes perceptively to their colours. To address this question we: (i) characterized the visual system of Tripterygion delaisi, which possesses fluorescent irides, (ii) separated the colour of the irides into its reflectance and fluorescence components and (iii) combined these data with field measurements of the ambient light environment to calculate depth-dependent perceptual chromatic and achromatic contrasts using visual modelling. We found that triplefins have cones with at least three different spectral sensitivities, including differences between the two members of the double cones, giving them the potential for trichromatic colour vision. We also show that fluorescence contributes increasingly to the radiance of the irides with increasing depth. Our results support the potential functionality of red fluorescence, including communicative roles such as species and sex identity, and non-communicative roles such as camouflage
Dietary fibre in Europe: current state of knowledge on definitions, sources, recommendations, intakes and relationships to health
Research into the analysis, physical properties and health effects of dietary fibre has continued steadily over the last 40-50 years. From the knowledge gained, countries have developed guidelines for their populations on the optimal amount of fibre to be consumed each day. Food composition tables from many countries now contain values for the dietary fibre content of foods, and, from these, combined with dietary surveys, population intakes have been determined. The present review assessed the uniformity of the analytical methods used, health claims permitted, recommendations and intakes, particularly from national surveys across Europe and around the world. It also assessed current knowledge on health effects of dietary fibre and related the impact of different fibre types on health. The overall intent was to be able to provide more detailed guidance on the types of fibre which should be consumed for good health, rather than simply a total intake figure, the current situation. Analysis of data indicated a fair degree of uniformity in the definition of dietary fibre, the method used for analysis, the recommended amount to be consumed and a growing literature on effects on digestive health and disease risk. However, national dietary survey data showed that intakes do not reach recommendations and very few countries provide guidance on the types of fibre that are preferable to achieve recommended intakes. Research gaps were identified and ideas suggested to provide information for more detailed advice to the public about specific food sources that should be consumed to achieve health benefits
Women’s participation in teacher unions: Implications of a ‘triple burden’ for union gender equality strategies
Amidst declining union influence, teacher unions have retained power. However, work intensification, arising from increasing reform in school education, has potentially undermined union participation, particularly women’s. Using a mixed-method approach, this article examines how the tangled combination of women’s paid work, union participation and family/domestic responsibilities (the ‘triple burden’) affects women’s roles as unionists. Examining the case of Australian teachers, the article finds that while demands of ‘work’ and ‘life’ can stifle union participation, it is specifically the cultural and historical legacies in unions that hinder women’s participation. The findings offer new insights around issues affecting the participation of women in female-dominated unions, and the intersection between union organisation and operation and the member-workers whom they represent. </jats:p
